i had 1 question, whenever i want to upgrade my firmware, do i had to redo everything all over again to make the phone back to the stage before i update? i don't know whether my steps are correct or not. @.@.

1. Download firmware from samfirmware and update via Odin.
2. Root and install kernel
3. Ext2Sd
4. restore backup from titanium backup.

sometimes some apps is not running, and i had to uninstall it and re-install, is that normal?

i want to ask ho.. is there any website or guide that i can refer to learn all the function and features of Note 2 ar? @.@
